No. I have never done this. I have done it three different ways.
1. Pod Farm open, running independently of the DAW. Recording input set to "dry" so that even though i HEAR the processed signal, what gets recorded is the dry signal. After this, then I apply the VST. This results in a bad, muffled sound.
2. pod farm open, input set to processed signal. What I hear is what gets recorded, so there is no need to use a VST. This results in the same exact degradation of the sound. Muffled, buzzy, low quality.
3. as you said, from the UX2 to the DAW with pod farm completely off. This way, I cannot hear what I am playing! It's useless to me ebcause if I want to record with a heavy metal tone but I just hear a clean tone, I can't play! Not only that, but this also does not solve the sound degradation issue.
I need pod farm open so that I can hear my own playing. It is possible to simply set it to input a dry signal so that effects can be added after recording. this does NOT solve the issue.
